[Splitter]

Hi all

I've been fixated with a splitter

Virgin Media, on a cable, is bringing me internet through the wall and into the superhub in the living room. Outside the house in that little Virgin Media cover I've connected a splitter to the prexisting cable that goes round the back of the house and on the first floor bedroom. So I've split the cable but I've still got good enough internet through the ground floor Super hub.

I'd like to ask, What can I do with the second cable that goes in the bedroom upstairs?
(I've already connected an ancient tv box and it plays at least 5 tv channels without subscription bbc1,bbc2,itv1,c4,c5)

Can I configure a router so I can have a separate network upstairs?
can I have internet through that 2nd cable somehow?

I'd like to use it but I dont know how. And I dont want to touch the superhub on the ground floor that is in working order.
